The complexity of coloring graphs without long induced paths
We discuss the computational complexity of determining the chromatic number of graphs without long induced paths. We prove NP-completeness of deciding whether a P8-free graph is 5-colorable and of deciding whether a P12-free graph is 4-colorable. Moreover, we give a polynomial time algorithm for dec...
